| Neste trabalho foi estudada a capacidade de parasitismo de Trichogramma pretiosum Riley linhagem bonagota, em ovos de Bonagota salubricola (Meyrick), às temperaturas de 18, 20, 22, 25, 28, 30 e 32ºC. Avaliou-se o número diário de ovos parasitados, a porcentagem acumulada de parasitismo, o número total de ovos parasitados por fêmea e a longevidade de fêmeas. O parasitismo durante as primeiras 24h oscilou de 1,6 (32ºC) a 8,8 (22ºC) ovos parasitados por fêmea de T. pretiosum. O parasitismo acumulado de ovos de B. salubricola atingiu 80% no período de 1 a 4 dias a 20°C e 32ºC, respectivamente, e somente no 7º dia, a 18°C. Na faixa térmica de 18°C a 22°C foram obtidos os melhores resultados para o total de ovos parasitados por fêmea, sendo de 35,4 a 24,6,... |

| Euselasia eucerus (Hewitson, 1872) (Lepidoptera: Riodinidae) is a Brazilian native species commonly found in Eucalyptus plantations. Biotic mortality factors of this defoliator were studied in a Eucalyptus urophylla plantation in Minas Gerais State, Brazil aiming to identify natural enemies and their impact on this insect. Euselasia eucerus had biotic mortality factors during all development stages. The most important were Trichogramma maxacalii Voegelé and Pointel, 1980 (Hymenoptera: Trichogrammatidae) during egg stage (48.9%), a tachinid fly (Diptera: Tachinidae) during larval stages (10%) and Itoplectis sp. (Hymenoptera: Ichneumonidae) during pupal stage (52.2%). The parasitism rate was higher in the basal part of the plant canopy (37.8%). |

| Mass rearing of parasitoids depends on choosing appropriate alternative hosts. The objective of this study was to select alternative hosts to rear the parasitoid Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae). Pupae of the lepidopterans Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae), Bombyx mori Linnaeus, 1758 (Lepidoptera: Bombycidae) and Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae) were exposed to parasitism by females of P. elaeisis. The duration of the life cycle of P. elaeisis was 21.60 ± 0.16 and 24.15 ± 0.65 days on pupae of A. gemmatalis and B. mori, respectively, with 100.0% parasitism of the pupae and 71.4 and 100.0% emergence of parasitoids from the first and second hosts,... |

| Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae) is a gregarious and polyphagous parasitoid mainly of Lepidoptera pupae. The objective of this paper as to study the developent of parasitoid on Bombyx mori L. (Lepidoptera: Bombycidae) pupae exposed to one, nine, 18, 27, 36, 45 or 54 female P. elaeisis, respectively. The females of the parasitoid remained in contact with pupae for 24 hours in glass tubes (14.0 x 2.2 cm), packed in a climatic chamber regulated at 25 ± 2°C, 70 ± 10% relative humidity and photo phase of 12 hours. With the exception of density 1:1 (72.72%), in other densities parasitism was 100%. Adults of P. elaeisis did not emerge from pupae at densities of 1:1 and 9:1, but 100.0% of parasitoid emergence was observed at the... |
